Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic structures, in particular to a multi-hole inflow counter-flow energy dissipation structure of a hydraulic structure. Background Art

[0002] A dam is a water-retaining structure that intercepts water flow in rivers and channels to raise water levels or regulate flow. It can form a reservoir, raise water levels, regulate runoff, and concentrate water head. It is used for flood control, water supply, irrigation, hydropower generation, and improved navigation. However, when the dam is releasing or draining water, the water flow is large and can easily destroy the river channel below the dam.

[0003] After searching, a Chinese patent with the announcement number CN210368884U discloses a multi-porous inflow hedging and energy dissipation structure for hydraulic structures, including a dam and a bottom plate. Dams are fixed to both left and right ends of the top surface of the bottom plate. A pipe is fixed to the inner cavity of the dam. The pipe is rotatably connected to the first straight plate through a first rotating shaft. An adjustment mechanism is fixed to the lower end of the first straight plate. The outer side of the adjustment mechanism is fixed to the dam. A buffer mechanism is fixed to the middle of the top surface of the bottom plate. The multi-porous inflow hedging and energy dissipation structure for hydraulic structures, through the connection and cooperation of the hydraulic cylinder, the first straight plate and the hydraulic rod, controls the hydraulic rod inside it to move in and out, so as to lift and lower one end of the first straight plate, thereby controlling the height of the water flow outflow, thus solving the problem of inconvenience in controlling the water outflow height of the dams on both sides, and solving the problem of still large kinetic energy of the water after hedging through the connection and cooperation of the block, spring and base.

[0004] However, in the above technical solution, only two hydraulic cylinders are used to adjust the angle of the first straight plate and thus control the height of the water flow. However, when the dam releases flood water, water flows continuously from the outlet and falls on the buffer mechanism. The continuous and stable output of the water flow will squeeze the spring, and the continuous pressure will make the spring unable to rebound. The spring will continue to remain in a compressed state, and the force cannot be dissipated by the rebound of the spring. Utility Model Content

[0023] Example 3

[0024] like Figure 2-Figure 4 As shown, the utility model proposes a multi-hole inflow counter-energy dissipation structure for hydraulic structures. Compared with the second embodiment, the present embodiment records the detailed structure of the buffer assembly, which includes a fixed seat 5, a buffer seat 6, an elastic member 7, a guide rod 8 and an intermittent motion assembly. The fixed seat 5 is connected to the hydraulic structure box 1; the buffer seat 6 is arranged parallel to the fixed seat 5 and is arranged above the fixed seat 5;

[0025] In an optional embodiment, the buffer seat 6 is provided with symmetrically arranged inclined surfaces, and a plurality of staggered buffer blocks 9 are connected to the inclined surfaces; the overall cross-sectional shape of the buffer seat 6 is an isosceles triangle;

[0026] Multiple elastic members 7 are evenly spaced along the length of the fixing seat 5, and the two ends of the elastic members 7 are respectively connected to the fixing seat 5 and the buffer seat 6; the elastic members 7 are springs; a guide rod 8 is connected to the buffer seat 6, and the other end of the guide rod 8 is disposed in a through hole provided in the fixing seat 5; an intermittent motion assembly is connected to the fixing seat 5; when the intermittent motion assembly is in use, the moving end of the intermittent motion assembly moves vertically away from or toward the buffer seat 6, causing the buffer seat 6 to undergo pressure changes and reciprocate to counteract the water flow and dissipate energy;

[0027] The intermittent motion assembly includes a driving device 10, an output shaft 11, a reciprocating screw 12, a limit block 13, a moving seat 14, a moving plate 15, a blocking block 16 and a multi-stage telescopic rod 17. The driving device 10 is connected to the fixed seat 5, and the output end of the driving device 10 is connected to the output shaft 11; the driving device 10 is selected from but not limited to a motor, and the motor is waterproof; the reciprocating screw 12 is connected to one end of the output shaft 11, and the reciprocating screw 12 is connected to the limit block 13 at one end away from the output shaft 11. The moving seat 14 is threadedly connected to the reciprocating screw 12, and the moving plate 15 is connected to the moving seat 14. A plurality of water outlets are provided on the moving plate 15, and a plurality of blocking blocks 16 are distributed around the circumference of the central axis of the reciprocating screw 12. The blocking block 16 is connected to the moving plate 15, and the blocking block 16 cooperates with the notch provided on the buffer seat 6. There are a plurality of multi-stage telescopic rods 17, and the two ends of the multi-stage telescopic rod 17 are respectively connected to the fixed seat 5 and the moving plate 15;

[0028] In an optional embodiment, the fixing seat 5 is connected to a plurality of parallel spoilers 18 , and the spoilers 18 are connected to staggered blocks; the blocks can further block the water flow passing through the spoilers 18 to reduce its flow rate.

[0029] In summary, when the present invention is used, the staff controls the two telescopic devices 3 to start, and the telescopic end of the telescopic device 3 contracts to drive the rotating plate 4 to rotate with its hinge as the center of the circle, and the rotating plate 4 changes from a state of being in contact with the notch on the hydraulic structure box 1 to being away from the notch, and the water flows into the interior of the hydraulic structure box 1 from both sides. Because the water flows on both sides are at the same height, the water flows into the cavity in the hydraulic structure box 1 and collides with each other to eliminate the force, and then the water flows fall onto the buffer seat 6. The buffer seat 6 is compressed by the pressure of the water flow and approaches the fixed seat 5. At the same time, the buffer seat 6 will also drive the guide rod 8 to move synchronously to guide the buffer seat 6. The water flow passes through the inclined surface of the buffer seat 6 and the buffer block 9 it carries to further reduce the water flow. When the intermittent motion component is started, the start of the driving device 10 will drive the output shaft 11 to rotate through its output end, and the reciprocating screw 12 on the output shaft 11 rotates, and the moving seat 14 on the reciprocating screw 12 moves along the reciprocating The screw 12 moves and the movable seat 14 moves down and approaches the fixed seat 5. At this time, the block 16 on the movable plate 15 gradually moves away from the notch on the buffer seat 6. The water on the buffer seat 6 is discharged through the notch, and its flow path is optimized to reduce the direct collision and friction with the buffer seat 6. The pressure on the buffer seat 6 is therefore reduced, thereby reducing the force on the elastic member 7 and causing it to rebound, and the buffer seat 6 moves up. As the reciprocating screw 12 continues to rotate, the movable plate 15 and the block 16 move up and gradually block the notch on the buffer seat 6. At this time, the flow path of the water flow is cut off, the contact and collision between the buffer seat 6 and the water flow increase, and the pressure on the buffer seat 6 increases. The buffer seat 6 moves down and compresses the length of the elastic member 7 and approaches the movable plate 15 and the block 16. Then, as the reciprocating screw 12 continues to rotate, the block 16 and the movable plate 15 move away from the buffer seat 6, and the notch on the buffer seat 6 opens again. Repeating this action can keep the buffer seat 6 in a moving state at all times, and the water flow is offset and dissipated through the collision and contact between the buffer seat 6 and the water flow.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
